How different are Law and Grace according to Les?
Law and Grace are two totally different concepts, differing as much as pitch midnight differs from high noon sunlight. The Lord's Prayer is legal, under Law. Romans 6:14-15 says you are not under Law but under Grace, so the old Adamic nature shall not have dominion over you.
Les explains that in Matthew chapter 6 the Lord's Prayer is under the Law, so its theology or doctrine is legal—it is Law. He contrasts this with Romans 6:14-15, where Paul says that sin or the old Adamic nature shall not have dominion over you because you are not under Law but under Grace. Les is amazed how many people in the Bible Belt have no concept of the difference between Law and Grace; they don't know there is any difference. But he says the difference is as great as between pitch midnight and high noon sunlight. These are two totally different concepts.
For sin shall not have dominion over you: for ye are not under the law, but under grace.
